On an LS motor, IIRC, it's a rather easy DIY job, if you buy one outside the dealer you may be able to buy one cheaper but get a good quality one, like an AC Delco which is OEM.
Reviews of AC DELCO parts For Business

I would get a Denso or AcDelco reman, no cheap crap since they're a bit of a pain to replace.
I would rather do it once and have it last for 100k+ than to do that repair 2x.
But its a Ford truck/suv and the alternators ALWAYS go bad on them. Word to the wise, buy an AC Delco replacement or Ford OEM, anything else will just die again-they always do.
Only use the factory AC-Delco 41-987 plugs.
OEM ACDelco drums solved the problem.
Currently I have ac delco batteries in every car I own. I work at a Cadillac dealership though so I get good prices on them and they're good batteries.
I paid $42 for the ACDelco iridium plugs, $45 for the ACDelco pro wire set.
I bought six ac delco spark plugs from Rockauto and half were made in France and half were made in the US. There are very slight differences like the diameter of the electrode and how deep the plug is on the end that goes into the cylinder. Even one of the US plugs is different from the other two.
I have a 1986 blazer and replaced the spark plugs with ac delco factory spark plugs purchased from napa, about 2 months later I was driving the vehicle and the vehicle had a miss then starting blowing out oil from the Pcv vlave from excessively high crank case pressure after electrode fell out.
I had previously used Wix brand filters, but the site I order from only had AC Delco, so that's what I was trying to install. The filter model is TP3018. The filter is too close to the engine block to get the threads to line up properly.
